I'll chime in that I paid about 1 month ago $165 + $10 shipping for the chrome version Granatelli/Pro-M 75mm.
My favorite power mod to date. I felt better throttle response immeadiately and felt so much stronger that I dynoed it (see dyno forum).
Gained 12 HP/9 lb/ft with combination of KKM, custom big airbox, the 75mm MAF meter, and I shortened the accordian airhose (to make it fit) compared with the stock filter, airbox, & MAF meter. I feel the MAF meter was the single biggest contributer. But I also have exhaust mods and an optimized throttle body so I was set up to really respond to opening up the intake. Can't say what will happen with stock exhaust or filter, but Kenneth with your set up I say go for it.
